This entry is being used for tracking a regression from 2.6.33. Please don't
close it until the problem is fixed in the mainline.
I hit that with opensuse factory today. echo disk > /sys/power/state works fine there. The kernel is -rc2-git3 (plus other patches of course). I'll look into that later if noone beats me to it.

patch for the issue
I'm not sure whether the second paragraph in the changelog holds. For me it works.
OK, I assume you have tested it both with and without CONFIG_DEBUG_BLOCK_EXT_DEVT.
I guess it should be pushed to Linus soon.
I wonder which change broke it, though.

I will bisect it later and make a note here.

I'm confused. I can reproduce it in 2.6.33 with DEBUG_BLOCK_EXT_DEVT set too. But suse with 33 and that option set worked OK. Waiting for Jiri's input.
